Using the Jianninxia Bridge as the experiment object, we set dynamic loading test on it, and did theoretical analysis on its natural vibration characteristics by using large-scale general finite-element software. After the comparative analysis between the collected datas and the theoretical analysis datas, we find that the measurement of the natural vibration frequency is greater than the theoretical analysis value; and the measured value of impact coefficient is less than the theoretical value; therefore, it indicates that this bridge’s actual structural rigidity is greater than its theoretical rigidity, but lack of the impact resistance.
This paper mainly analyzes the current problems existing in oral English teaching with application of multimedia technology and network-based environment on base of constructive learning theory as well as current reform situation. By providing diverse effective strategies, both scientific application of multimedia technology and oral English teaching quality could be achieved to its best.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
